Why a 'Half Car Seat, Half Man' Was on the Road

A van that appeared to have no driver made headlines when it was spotted in Arlington, Virginia, last week. But when News4's Adam Tuss saw the van on Monday and looked inside, he saw that it did have a driver: a man dressed in a costume made to look like just a car seat.

From the road, the unmarked gray van eerily looks like it's moving without a driver. The entire front seat looks empty. But when Tuss looked inside, he saw a man wearing a beige and black costume that covered his entire torso.

After multiple inquiries by News4, the Virginia Tech Transportation Institute said Monday afternoon that the van and van driver are part of a study they are conducting on driverless cars. The worker was wearing the uniform he was supposed to wear.

"The driver's seating area is configured to make the driver less visible within the vehicle, while still allowing him or her the ability to safely monitor and respond to surroundings," a statement from the institute says.

Virginia Tech declined to make the half car seat, half man -- as Tuss put it -- available for an interview.

Arlington County officials were involved in the planning for the study, a Virginia Tech spokeswoman said. Arlington was selected because "it is representative of the urban areas for which automated vehicles are currently being considered," she said.

CORRECTION (Aug. 8, 2017, 9:30 a.m.): An earlier version of this story said the driver ran a red light, in apparent attempt to evade News4. But a spokeswoman for the Virginia Tech Transportation Institute says a thorough review of the in-vehicle camera showed the driver passed through a yellow light.
